Hi all,

I am reading the wall film vaporization model in CONVERGE, and as the manual says there are two models: uniform Temperature model and discretized temperature model;

In the udf source code file "user_film_evap.c" it shows the uniform temperature model does not consider the condensation phenomenon from gas phase to liquid parcel.

My question is for discretized temperature model, does it consider condensation phenomenon or not? In source code file "user_film_thick_evap.c", the vaporization heat flux is directly called by function "SHARED_get_parcel_Ldmdt()", however I cannot find details about this function.

Appreciate for kind help from you guys!

Hi,

Condensation is not considered in wall_film_vaporization model.

Best,
